I guess it's the fact that size_t might (e.g. on 32-bit systems) be a
smaller type than lua_Unsigned, so the compiler might warn about the
truncation. But the value can't overflow a size_t, so there's no real
issue here other than the compiler warning.

In 5.4 lua_rawlen seems to return lua_Unsigned rather than size_t.
Obviously that can't be changed in 5.3.x.
